Open Portfolio window - yes, I can force the window below the button, but only by moving the dashboard partly off the top of the screen, to make enough room for the window below the button.
The size of the window seems to be an issue. Maybe this would work better if the window was of variable size, depending on the number of portfolios. I have one, and there's an awful lot of empty real estate in the window.
Logo - my suggestion is to remove it, because it doesn't add anything extra to what I can do with the entry in the taskbar (don't know if this still applies to win8?), and gets in the way too often.
